She's a nice fish, but she looks like she has hex, white stringy poo bigtime, I'd treat her if I were you.
Actually, when I feed my flowerhorns raw prawns a lot , they get white poop. It scared me at first because I thought it was hex but if I don't feed them too much raw prawns, their poop is normal. I was wondering when someone was going to say something about her white poop. Thanks for looking out, Ed.
